View source for Jacques Dudon

'''Jacques Dudon''' ({{IPA|fr|ʒak dydɔ̃}}) is a [[French people|French]] [[just intonation]] [[composer]] and instrument builder. He is best known for developing a series of [[photosonic]] disk ({{lang|fr|disque photosonique}}) instruments in the 1980s that produced sound from modulated light (a light source shines through painted glass discs; the resulting patterns of light are picked up by [[photo cell]]s and converted into a voltage which can then be treated as a sound signal).

The production of synthetic sound in this manner has been used in "optosonic" instruments since the early 20th century (for example the  [[Optophonic Piano]]). However Dudon's method is notable for the generation of tone which is produced by the overlapping of two or three discs, and the opportunities this design provides for [[timbral]] shifts by slowing one or more discs manually, thereby altering the waveform.

In the 1970s, he created 150 water instruments called "[[aquaphone]]s" (described in his pioneering book {{lang|fr|La Musique De L'eau}}<ref>{{cite book|last=Dudon |first=Jacques|title=La musique de l'eau|location=Paris|publisher=Éditions Alternatives|year=1982|isbn=2-86227-027-X|language=French}}{{page needed|date=May 2014}}</ref>), including a "flutabullum", a system of transforming [[flute]] sounds by recording them underwater).<ref>{{cite book|last=Hopkin |first=Bart|title=Musical Instrument Design: Practical Information for Instrument Design|location=Tucson, AZ|publisher=See Sharp Press|year=1996|isbn=1-884365-08-6}}{{page needed|date=May 2014}}</ref>

==Aquavina==
The '''aquavina''' was an [[experimental musical instrument]] created by Jacques Dudon.<ref>Hopkin, Bart (1996). ''Gravikords, Whirlies & Pyrophones: Experimental Musical Instruments'', {{page needed|date=May 2015}}.  Ellipsis Arts. {{ISBN|978-1-55961-382-8}}.</ref>

It was essentially a variant of the [[Appalachian dulcimer]], but with a metal resonator body partially filled with water.  The player would agitate the instrument while playing, resulting in a constant acoustic phasing effect within the instrument's [[harmonic]]s.
